They come pre gapped with collars to prevent the electrodes from getting bent .platinum and iridium plugs will have the surface damaged if you were to adjust them with a feeler gauge,like old plugs had to be gapped. ac or ngk plugs come pre gapped in the box.

What is the gap for a 2004 GMC envoy 4.2 liters

Natalie, our 4.2 engine only likes 1 sparkplug. AC Delco 41-103. This Iridium plug comes pre-gapped, to near the specs Mike posted. Don't try and gap these particular plugs yourself, easy to ruin them.

Spark plug gap specs for 2002 envoy SLE

Gap should be around 0.043"
Also, make sure to use only AC Delco 43-103 plugs, these are the OEM plugs and work best in these engines.

What is the gap for a spark plug on a 2004 gmc envoy?

.040 to .044" would be normal. The gap should listed on the emission sticker under the hood. Make sure you use the O.E. AC/Delco plugs. This engine will run on those the best!
